From this, using Sobolev's embedding theorem, standard iteration arguments
(see e.g. [1]})
and condition (REF ) on \(k\) , we obtain that
\(\operatornamewithlimits{ess\,sup}\limits _{B_{\rho /4}(x_{0})}w\leqslant \gamma \,e^{2n\lambda (\rho )}\bigg (_{B_{\rho /2}(x_{0})}|w|^{\,\frac{n}{n-1}}\,dx\bigg )^{\frac{n-1}{n}}+1.\)
